Charleston Tide Chart & Tide Times

Charleston tide times for the next 7 days

30-day Charleston tide table

In this 30-day table the highest crest and the lowest water land on different dates.

The lowest water in that table is a minus tide, under the datum.

Charleston tide profile for the next 12 months

Tide type: semidiurnal (two highs, two lows)

Two highs and two lows a day are the normal pattern in this window. 25 dates out of 365 carry a single crest. That even, repeating cycle is a semidiurnal tide.

On a two-crest date the lesser peak falls noticeably short of the greater peak. You can see the gap when you read both highs, but the second peak is still there.

The taller crest usually arrives around the middle of the day. Late morning and early afternoon hold that higher high water on a typical date.

How much the tide rises and falls

The average daily rise is 5.6 ft. The shore gains and loses a wide strip of beach between the lower low and the higher high. The range is moderate.

Spring peaks and neap lulls stay close. An ordinary day and the biggest day are the same kind of rise, not two different shores.

Low water below the datum is a regular event. It happens on 153 dates out of 365 dates that have a low. A minus reading is ordinary here, not a rarity.

The other published South Carolina station has a smaller average daily rise than this one.

Highest and lowest predicted tides of the next 12 months

The lowest predicted water of the window falls in winter, at -1.5 ft on January 23, 2027 at 2:01 AM.

That lowest water falls outside daylight, so the year's extreme is not a daytime exposure.

Best low tides for tide pooling in Charleston

Daylight exposure of the bottom is a regular seasonal event. Walkers get repeated chances, spread through the year, not one holiday weekend.

The next 12 months have 117 dates with a daylight minus tide.

Those daylight lows cluster from late morning through mid-afternoon. The useful window sits well after sunrise and well before sunset.

The daylight-minus dates come in two waves, one in the cool months and one in the warm months. A single season does not hold them all.

Moon phases and the tide

The month's tallest crest lands on the same date as the new moon or the full moon. The lag after the new or full moon, measured as the median across this window, is under half a day.

Charleston Harbor tidal currents

Tidal current predictions for this harbor come from NOAA station ACT6651, Charleston Harbor, off Fort Sumter. On October 10, 2026 the flood current is 1.74 knots (incoming) at 5:12 AM, toward 313 degrees, and the ebb current is 2.84 knots (outgoing) at 12:05 PM, toward 127 degrees.

In this 30-day current table the strongest flood is 2.24 knots (incoming) at 6:11 AM on October 27, 2026, and the strongest ebb is 2.98 knots (outgoing) at 1:11 PM on October 27, 2026. Slack water is the turn between those flood and ebb currents. Speeds are knots, not tide heights.

Charleston Harbor, off Fort Sumter, ACT6651, publishes 60 max floods and 60 max ebbs from October 9, 2026 through November 8, 2026. Max flood is the fastest incoming current; max ebb is the fastest outgoing current.

High tides vs. NOAA's minor flood level

NOAA's minor flood level for this station is 7.64 ft above MLLW (10.40 ft on the station datum; MLLW sits 2.76 ft above that datum).

No predicted high in this window exceeds that minor flood level.

Tides at nearby stations

High water at the nearest published station arrives earlier than it does here, by tens of minutes rather than by a couple of hours.

The rise at that neighboring station is about the same size as the rise here. The two pages differ in clock time more than in how far the water climbs.

That neighbor is on the same regional coast, tens to a couple of hundred kilometers off. It is a fair comparison for how the wave travels, and it is not the next pier.

Charleston tide questions

When is the lowest tide in Charleston over the next 12 months?

The lowest predicted water of the window falls in winter, at -1.5 ft on January 23, 2027 at 2:01 AM. That lowest water falls outside daylight, so the year's extreme is not a daytime exposure.

When are king tides in Charleston?

On this site a king tide is one of the 3 highest predicted highs in the window, not a flood warning. At Charleston those highs are 6.9 ft on October 1, 2027 at 9:31 AM (in daylight); 6.9 ft on September 30, 2027 at 8:41 AM (in daylight); 6.9 ft on October 27, 2026 at 9:06 AM (in daylight). The three highest crests in the window all fall in daylight. You can see those peaks without a lamp.

When is the best time for tide pooling in Charleston?

Daylight exposure of the bottom is a regular seasonal event. Walkers get repeated chances, spread through the year, not one holiday weekend. The next 12 months have 117 dates with a daylight minus tide. The daylight-minus dates come in two waves, one in the cool months and one in the warm months. A single season does not hold them all. Those daylight lows cluster from late morning through mid-afternoon. The useful window sits well after sunrise and well before sunset.

How much does the tide change in Charleston?

The average daily rise is 5.6 ft. The shore gains and loses a wide strip of beach between the lower low and the higher high. The range is moderate. Spring peaks and neap lulls stay close. An ordinary day and the biggest day are the same kind of rise, not two different shores.
